>
> The {{getCustom()}} function of {{KeeperRecordData}} as defined by the KSM
> SDK is permitted to return {{null}} (it is annotated {{@Nullable}}), however
> Guacamole's support for KSM assumes that it will always return a {{List}},
> resulting in a {{NullPointerException}} if it ever does return {{null}}:
> {code:none}
> java.lang.NullPointerException
> at
> org.apache.guacamole.vault.ksm.secret.KsmRecordService.getField(KsmRecordService.java:241)
> at
> org.apache.guacamole.vault.ksm.secret.KsmRecordService.getField(KsmRecordService.java:312)
> at
> org.apache.guacamole.vault.ksm.secret.KsmRecordService.getHostname(KsmRecordService.java:397)
> ...
> {code}
> Things should be corrected as necessary to handle {{null}} identically to an
> empty {{List}}.
